REVOLVING HAY-RAKE.

SPECIFICATION forming part of Letters Patent No. 255,291, dated March 21 Application filed November 29, 1881. (No model.)

To all whom it may concern Be it known that I, EDWARD HUBER, of Marion, in the county of Marion, and in the State of Ohio, have invented certain new and useful Improvements in RevolvingHorse Hay- Rakes; andI do hereby declare thatthe following is a full, clear,and exact description thereof, reference being had to the accompanying drawings, and t0 theletters of reference marked thereon, making a part of this specification.

This invention relates to horse hay-rakes wherein the teeth are inserted into a head which is allowed to revolve in journal-bearin gs on the, ends of the standards to which the arms or handles are pivoted.

The nature of my invention consists in the combination of spring-plates having catches struck on their free endsand fixed to the arms or handles with engaging-plates applied to the revolving rake-head and the teeth thereof for the purpose of holding the rake in a working position for-gathering a load and allowing the attendant to release the rake for discharging the loads, as will be hereinafter explained.

In the annexed drawings, Figure 1 is a perspective view of the rake held in working position by the spring-catches. Fig. 2 is a perspective view of one of the spring-catches. Fig. 3 is a perspective view of a portion ot'the rake-head and two teeth, showing the shoes K. Fig. 4 is a transverse section in detail.

A is the rake-head, and B the rake-teeth, which are of the ordinary construction. The lower ends of the vertical standards 0 are secured to the rake-head A by proper straps and in such a manner that the head will freely revolve in said straps. To the tops of these standards 0 are secured the draft-bars E, which are connected together by the cross-tie F. About midway between the draft-bars E and the head A are pivoted the handles G, which are secured together by a cross-tie, H, and provided with a handle, I. The metal springs J are provided with catches a, which are struck or punched directly out of the springs.

These springs are rigidly secured at their upper ends to the handles G, so that their lower ends project downward for the purpose of allowing the space I) between the catches a to engage with the edges of the plates K, which are secured to the rake-head A and to proper teeth. Thebottoms of these springs are rounded off and the front edges curved forward, as

. shown in Fig. 2, so as to conform with and fit of the handles, which causes the springs J to slide backward upon the upper faces of the When the operator deplates K until they pass to the notches 0, when the rake revolves, the lower ends of the springs J sliding against the bands L as the'rake revolves until the revolution is complete, when the projections to will again engage with similarplates, K, upon the opposite side of the head.

The advantages of my construction are as follows, viz: By making the plates K serve as shoes I save considerable expense, and by punching the stops at on thesprings'J, I obtain stronger detents, which will not get clogged, as was the case in my rake patented to. me January 21, 1865, No. 46,001. By curving the ends of the springs J, I am able to fit them more closely to the head, thus avoiding danger of clogging, and by combining with it the band L the rake revolves with less friction and wear. a

It will be seen that when the operator lifts the arms for the purpose of discharging a load the lower lug a will act directly on a plate K and tilt the rake at once.

What I claim is- 1. The combination, in a revolving rake, of the rake-head A, revolving in the standards 0, the plates K, notched at c and secured to the rake-head and tines, the handles G, pivoted to the standards 0, the springs J, secured to said handles, and the two lugs or projections at a on said springs, one projection serving to hold down the rake-teeth in working 2. The combination of the rake-head adapted use in combination with the plate K, notched to to revolve in bearings of standards 0, the at c, for the purpose described. metal bands L, encircling the rake-head, the I In testimony whereof I affix my signature, spring catch-plates J, and the plates K, bear- 1 in presence of two witnesses, this 17th day of ing against said bands, substantially as speci- November, 1881. fied.
